Google for "dranger ffmpeg".  The original page is a tutorial page, but 
it is a tad out of date.  Some other repositories contain updated code.

Some demuxers may support multithreaded operation, albeit for most 
operations you gain little.  For that, you can use:

   AVDictionary* info = NULL;
   av_dict_set(&info, "threads", "auto", 0);

   avcodec_open2( video_ctx, video_codec, &info );
